Chael Sonnen Issues Official Challenge To Fabricio Werdum

The Abu Dhabi Combat Club (ADCC) held an event in Espoo, Finland this past September. During the event, former UFC title challenger Chael Sonnen took on two-time ADCC 145-pound champion Leo Vieira. After no points were scored in their grappling match, Sonnen earned a referee decision victory for the championship. Now, it would appear that the Bellator fighter is looking to take on a former UFC heavyweight champion.

In an interview with Flo Grappling, Chael Sonnen recently decided to put his ADCC title on the line by calling out former UFC heavyweight champion and Brazilian jiu-jitsu phenom Fabricio Werdum.
